Periodic Variation in Karst Stream Losses
A cave taking water from an ephemeral stream periodically reroutes surface and subsurface drainage because of a plug that forms 10 m below the main entrance to the cave. The plug of sand,...

Preliminary Studies of a Karst Warm Spring in Mt. Kräuterin, Austria
A warm spring occurs at the west foot of Mt. Kruterin, characterized by relatively higher temperature (17.4°C) and sulfate concentration (162 mg/L) against with the regional background...

Hysteresis Effect of Karst Vadose Zone in Spring Kr5, Mt. Kräuterin, Austria
Hysteresis effect is considerable in Spring Kr5, involving a chain of processes of recharge-infiltration-discharge. The lag time of each process to another can be briefly summarized and...

Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...

Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...

Probabilistic Risk Assessment for Tailings Impoundment Founded on Paleokarst

Rethinking Foundation Design in Karst Residuum

Geophysical Investigation of Karst Collapse Features for a Proposed Waste Rock Stockpile Irian Jaya, Indonesia

Effects of Karst Environments on Streamflow in South Georgia

Geostatistical Description of Hydraulic Properties in Karst Aquifers: A Case Study in the Edwards Aquifer

Ataturk Dam - Hydrogeological and Hydrochemical Monitoring of Grout Curtain in Karstic Rock

Flood Damage Mitigation Efforts in a Small Mountainous Community in Jamaica
About 60 percent of the mountainous Caribbean island of Jamaica is underlain by karstic limestone. 'Sinkholes' in this limestone form the natural outlets to many surface waters. During...

Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...

Exploration/Grouting in Cambro-Ordovician Karst

Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...

Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...

Quantitative Dye-Tracing of Karst Ground-Water Flow
Analysis of the results of repeat quantitative dye traces between a sinkhole and a spring used for public water supply were used to describe predictive relations between discharge, mean...

Evaluating Sinkhole Hazards in Mantled Karst Terrane
Sinkholes are the most serious geologic hazard in karst terrane because they can damage structures, drain ponds and lakes, and allow direct infiltration of groundwater contamination. The...

Geophysical Exploration for Cavity Detection in Karst Terrain
Detection of poor quality rock and voids has been a major research activity of the U. S. Army Engineer Waterways Experiment Station (WES) since the mid 1970's. The principal...

Exploration of Karst Conditions in Central Florida
Walt Disney World, which comprises some 28,000 acres (11,000 ha) in central Florida, is underlain by cavernous limestone and is characterized by karst topography; with distinct low ground...
